design procedure for ADPLL parameter determination

System design procedure for Type-II second-order ADPLL 

Reading the following reference, learn how to analyze the ADPLL. There is an error in calculating the resistor of the loop filter. It was corrected in the matlab code.

For better learning and understanding the publication, I created a mindmap reference and matlab code.

Simulink model of Scrambler and Descrambler

Scrambler often referred as randomizer basically removes long stream of zeros and ones from the data. It is used in wireless transmitter and receiver chain. Descrambler is the reverse operation.

HSCPIE Files Explanation

HSPICE Major Files Explanation

Input files:

1. netlist source: filename.sp
2. initialization: hspice.ini
3. design configuration: filename.cfg

Output files:

• run status: filename.st0
• output listing: filename.lis
• graph data files

gRAPH DATA	ANALYSIS RESULT
*.tr0	transient
*.sw2	dc
*.ac1	ac

in general, you only need to know about some of these files: source file, output listing, and graph data.

source file (.sp)

The source file contains your circuit description and all options and analysis setup.

 

For example:

Output listing(.lis)

This is one of the most important files in HSPICE as this file lists all results obtained from the simulation. This file contains (in order of listing in the file):

• HSPICE licensing information
• Listing of the circuit
• Results form the analysis of the circuit (.op, .print, .plot, .measure, .ac, and .tran in order of their appearance in the source file)
